Channel Configuration

Protocol Options

  • Maximum size of blocks: Defines the maximum of addresses in a read block.

 Settings

TCP/IP:

  • NodeConnections: Defines the maximum number of parallel requests that will be sent to each node (asynchronous communication)


Node Configuration

Station Configuration

TCP/IP:

  • Station syntax: <IP address> ; <Port number>

Where :

  • <IP address>: IP address of the slave device in the modbus network
  • <Port number>: TCP port where the slave device is listening (default is 44818)

E.g.: 192.168.1.1 ; 5551


Points Configuration

The syntax for the MelsecFX communication points is: <Operand> <Address>

Where :

  • <Operand>: Represents the Device Memory :
  • <Address>: Address number
